When declared as a class-level annotation, @Commit defines
the default commit semantics for all test methods within the test class
hierarchy. When declared as a method-level annotation, @Commit
defines commit semantics for the specific test method, potentially
overriding class-level default commit or rollback semantics.

Warning: @Commit can be used as direct
replacement for @Rollback(false); however, it should
not be declared alongside @Rollback. Declaring
@Commit and @Rollback on the same test method or on the
same test class is unsupported and may lead to unpredictable results.
